Duro Mountain Presta Valve Tube

Duro Mountain Presta Valve Tube

Duro inner tubes come in several widths and diameters. The varying widths and diameters are super accommodating. These inner tubes can be used to tire widths between 1.0” - 1.5” & 2.1” - 2.4”. That’s a huge range! Buy more than you think you'll need and keep a few in your bag as spares.

One thing we have discovered is that there are only a handful of bicycle inner tube manufacturers across the globe. Many, if not all inner tubes, come from a small handful of suppliers in Asia. This essentially means that no matter the tube brand, we’re all riding the same tubes.

Thus, we've sourced these tubes direct from the manufacturer and cut out the middle man, passing the savings along to you. This is great for you because you’ll be getting a high quality tube at a great price. Nearly nowhere else can you buy an inner tube for such a low price anymore. Stop getting gouged at the counter and buy your tubes in bulk from Jenson USA!

Choosing the Correct Tube:Choosing the correct tubes for your tires is crucial to the proper performance of your bicycle. If you need help, please call or chat with our Gear Advisors for assistance.

Step 1: Find the wheel size, or diameter for your mountain bike. It is usually printed on the tire. (26”, 27.5"/650b, or 29”. If your tire says something else, such as 700 x 23c, you will need to look at our Road tube selection.

Step 2: Choose the correct width. If your tire says 29 x 2.25", your tire is 29 inches in diameter and 2.25 inches wide. You can then use a tube labeled 29 x 2.1-2.4". Tubes fit a range of tire widths. Make sure your width is within the tube's range. Do NOT use a tube size not labeled for use with your tire.

Step 3:Select a valve stem length that will clear your rim by at least a few centimeters to clear your pump head for easy inflation. Measure your rim depth with a ruler, then simply subtract the depth (vertical thickness) of your rim in millimeters from the valve length. It should be at least 20mm, preferably around 30mm. If it is below that measurement, it will not fit your rim. You will need to buy a tube with a longer valve stem.

Jenson USA you kick butt! Thank you again and again for keeping my passion rolling! Wether I'm buying an intertube or a complete bike I feel confident in my purchase and that if its not right you will help me make it right.

I can't say enough about the website and the mobile app. It is really what seems to matter to me the customer. I work in IT so I spend a lot of time on web portal's and support sites. I know a well made customer oriented expierence when I see one.

You guys hiring IT staff!? Just kidding... but seriously I would give my left #$%^@! to be a part of such an awesome company and skilled team of professionals! Thanks again for doing what you do!

These tubes are very affordable, and they do what you expect them to do. -hold air. My only complaint is with the packaging. The first ones I ordered came in a Mylar looking bag. when I ordered a different size, it came in a clear plastic bag and didn't tell you what size it was. Obviously, I know what I ordered, plus the packing slip tells you what it is. But, what if you ordered two different sizes on the same order? For the price, I can live with that little annoyance and I still give them 5 stars.

its a tube. what else is there to say? its cheap, which helps and hurts. its got quite a bit of rubber actually which makes me think they will last a while but its also slightly heavier if youre worried about those things. im not personally and would much rather not ever get a flat again. hoping they keep lasting but so far so good on some technical single track trail. most dependent on the tire anyway.

Seems like a decent tube, but was a real pain to discover that the valve core was non-removable. Don't know why any valve core would be non-removable except for companys cheaping out. Makes me wonder what other "cost savings" are inherent in these tubes that I don't know about. I guess I should have read the reviews better, saw this "feature" after I had already purchased one (thank goodness I only bought one).

I thought the price was great, so I ordered 5 to keep me stocked up. Wrong!All 5 are now flat-the valve stem develops a separation right at the collar junction. I would flat, replace the tube, then pump up the old tube and it never lost air, until the valve stem was moved. I have 4 of these with the same issue(5th was tossed at the trailhead trash can)

I've been using these tubes in 27.5 plus tires with great results. They are light, especially for the price. The short presta valve is very nice and looks clean when installed. These are a great off season alternative to tubeless and I'll continue to buy them in the future.

Good tubes at a great price - never had an issue with any of the Duro tubes I've purchased. I run tubeless on the bike, but always throw one of these in for those times when sealant just won't plug the hole. Haven't let me down yet.

My LBS only sells 26x1.5 tubes with presta valves, nothing wider. These tubes are much thicker than the 1.5 tubes I was using and help prevent flats. I commute 16 miles round trip ,5 days a week. After 1 month I havn't had a single puncture.

I've tried the Duro road tubes and Duro road tires and both have been great products especially at the price that Jenson offers them at. Hopefully the mountain tubes will perform as well as the road tubes.
